PIPE-THIMBLE.

SPECIFICATION forming part of Letters Patent No. 489,068, dated January3, 1893.- Application filed August 29. 1892. Serial No. 44:4,i67. (Nomodel.)

T0 at whom it may concern:

Be it known that I, REUBEN Z. OAssEL, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented certain new and useful Improvementsin Pipe-Thimbles; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The object of my invention is to provide a neat, simple, and inexpensivethimble which is adapted to receive different sizes of pipe.

My invention consists in an improved form of main ring or thimble andthe way of connecting the reducing thimble.

In the accompanying drawings, Figure l is a front view; Fig. 2 is asectional view taken on the line cc-m of Fig. 1; and Fig. 3 is aperspective view of the main thimble or ring.

A represents the outer or larger thimble which will preferably be madeof cast iron. This thimble will comprise a tubular portion 1, theoutwardly extending flange 2, and an inwardly extending flange 3. Uponthe inner side of the tubular part are pins 4.

The letter B designates a reducing thimble or ring which tits within thetubular portion of the outer thimble and as its name suggests enablesthe user to diminish the size of the pipe opening in the wall. Thisthimble or ring B comprises a flat portion 5 with a flange 6 projectingrearwardly from the edge of its opening. In the edge of the fiat portionare notches '7 which allow the thimble to pass the pins 4: which whenthe thimble is slightly turned hold the latter in place. The size of theopening in the reducing thimblemay, of course, be such as circumstancesrequire. A short piece of sheet metal iron pipe is secured to the castiron thimble A by turning its edge down upon the flange 3, as shown inFig. 2. A lip O which projects from the lower Side of the mouth of theouter thimble may also be provided to prevent streaking and otherdisfigurement of the wall by the falling of soot, ashes, &c., when apipe is withdrawn from the thimble. A plate for closing the pipe openingwill have notches in its edge so as to be capable of insertion andfixation in the outer thimble in a manner like that in.

which the reducing thimble is applied and secured.

By constructing the outer thimble as herein described, that is, with thecylindrical portion 1 and pins 4 so that the closing plate may be setback beyond the plane of the surface of the Wall the stove pipe openingmay he papered over and its presence, so far as appearances indicate,obliterated.

Among other important advantages of my thimble are that it is neat inappearance, extremely simple, cheaply constructed, substantial, anddurable in use.

The various sizes of reducing thi mbles may be kept in stock by dealersso that it will be necessary to purchase only that size which is needed.

What I claim and desire to secure by Letters Patent is- In combination,the main thimble A comprising the cylindrical portion l, the outwardlyturned flange 2 at its outer end, and the inwardly turned flange 3 atits inner end adapted to receive a stove pipe, the pins 4 on theinterior of the cylindrical portion 1, and the reducing thimble B havingthe disk or plate-ring 5 constructed to fit within the cylindricalportion 1 and provided with notches 7 to receive pins 4 whereby thereducing thimble may be detach-ably secured to the mainthimble,substantially as shown and described.

In testimony whereof I aflix my signature in presence of two witnesses.

REUBEN Z. CASSEL.
